Andrej, that's odd, there should be a mca_pmix_pmix3x.so (assuming you built with the internal pmix)
what was your exact configure command line? fwiw, in your build tree, there should be a opal/mca/pmix/pmix3x/.libs/mca_pmix_pmix3x.so if it's there, try running sudo make install once more and see if it helps Cheers, Gilles On Mon, Feb 1, 2021 at 11:05 PM Andrej Prsa via devel <devel@lists.open-mpi.org> wrote: > > Hi Gilles, > > > it seems only flux is a PMIx option, which is very suspicious. > > > > can you check other components are available? > > > > ls -l /usr/local/lib/openmpi/mca_pmix_*.so > > andrej@terra:~/system/tests/MPI$ ls -l /usr/local/lib/openmpi/mca_pmix_*.so > -rwxr-xr-x 1 root root 97488 Feb 1 08:20 > /usr/local/lib/openmpi/mca_pmix_flux.so > -rwxr-xr-x 1 root root 92240 Feb 1 08:20 > /usr/local/lib/openmpi/mca_pmix_isolated.so > > Thank you for your continued help! > > Cheers, > Andrej >
